MOP AND DUSTER CONSTRUCTION.

Application filed August 15, 1924. Serial No. 732,149.

The present improvements relate to devices of the mop and duster type for cleaning floors, walls, windows and other surfaces. Its principal objects are to provide a mop or duster according to which the cleaning element, usually called a swab, may be readily applied to the frame adapted to hold and carry it, and from time to time be readily removed therefrom, as for cleaning the swab or the frame, making repairs or replacing an old swab with a new one; and to provide such advantages in a device of simple construction and of few parts, and which may be of various forms, shapes and sizes according to particular uses or other considerations.

It is not broadly new to provide .a mop or duster having a removable swab, but so far as I am aware no such device has been suggested, prior to my present invention, aocording to which the swab may be applied or removed without considerable labor, patient effort, and loss of time.

In the accompanying drawings, which form a part of this specification, Figure l is a perspective of a preferred form of the improvements as embodied in a mop or duster of the elongated body type; Fig. 2 is a top plan of the device of Fig. 1 with the handle bracket broken away; Fig. 3 is a sectional view on the line 33 of Fig. 2; and Fig. 4: is a fragmentary section as on the line of Fig. 2.

Referring to Figs. 1 to 4, the device illustrated includes a body member or frame 10 of elongated form having flanges 11 integrally formed at each side thereof. These flanges are shown as upstanding, this arrangement being preferred since it leaves the bottom of the frame free of projecting parts likely under some conditions to contact and mar furniture or other objects being cleaned, and it also avoids some injury to the The cleaning element 17, usually called a swab, is to be understood as consisting of strands or lengths of cord, yarn or the like secured together and covered along one edge portion with a fabric binding 17 The construction of such and other cleaning elements suitable in the present device is well known and the one illustrated may be considered of any approved manufacture as to details. It diflers from hitherto-suggested swabs, so far as I am aware, in being continuous or in the form of an endless band or ring, the ends of a strip of swab having been stitched or otherwise secured together to produce it. It is not essential, however, that the swab be in the form of an endless ring. Whether endless or divided, when normally applied to a frame such as is shown in Figs 1, 2 or 5, it will be ring-like and will substantially surround the frame and lie along marginal portions thereof, as in contact with the marginal flanges.

An eyelet 20 is preferably .secured in the binding 17 of the swab at equally-spaced apart portions thereof, and when the swab is applied to the frame the projections 14 extend into these'eyelets respectively, provide anchoring means for the swab, and hold the swab readily releasably upon the frame.

The construction provides swab material at the ends of the device, and the metal parts are effectively covered by the relatively soft material, so that the marring of furniture and other objects contacted by these end parts of the device is avoided, and at the same time the presence of swab material at the ends provides means for cleaning in corners and other relatively small. spaces. The studs or projections 14: preferably terminate short of the thickness of the swab to avoid marring effects by their outer ends respectively.

Preferably substantially midway between the ends of the frame there is a constricted or throat-like portion formed by inclining the side walls inward from the relatively wide places at 1516 on one side and 17-18 on the other. This construction provides recesses, hollows or indentations in the frame at 22 on one side and 23 on the other. When the swab is normally applied to the frame, portions of the swab extend across these recesses respectively. The swab is of slightly less lineal measurement than is the periphery or margin of the frame where the swab is adapted to rest upon it. Eyelets 24 and 25 are securedointhe swab binding opposite the recesses respectively.

The flanges 11 on opposite sides are apertured at the recesses to receive the transversely-directed bolt 26, and this bolt passes also through the eyelets 24] and 25. By means of the wingaiut E'T the opposite portions of the swab at the recesses 22 and23' are drawn toward each other, and,;since the swab bridges these recesses when first appl-iedfthe' recessesa liordspace into which ;portions' o.t' the swab can be drawn. The

tl' reading .oi the thumb-nut upon the bolt draws the swab taut and in tightc'ontact withthe marginal portions or flanges of the .fr ame.

Nlaenlthe swab is thus drawn taut the sharp projections 15, 16, 1-7 andlS enter the .b fd sei'w e as locking means adapted f swab from movement in up and dot ,rlir'etiQns relative 'to' the frame.

There is verylittle longitudinal movement ojffthe mber theseprojections. The end proiecti'ons 14 anchor the swab against the pulling strains exerted bythe-bolt and nut,

which strains, in the construction shown,

come substantially equally 1 on both sides. In some constructions, however,such strains might come principally or entirely on one side, and in view ot'this disclosure those slrilled in the art will readily perceive how a considerable variety or arrangements of parts nay' be had without departing from the spirit of this invention. The projectionsl i also maintain the swab'against upandmlowirrfelative movement at the ends of the device. v v\Nhile such projections as 15 to 18 mightbe employed atthe ends, and

awhile the marginal portions of the frame may have various shapes having a view to holding the swab thereon, the construction illustrated isboth effective and relatively cheap. V v

The handle bracket 30 is of well-known .formf In Fig. 2 it is shownas being aperrtured. to accommodate the bolt 26, A simi- .larbracket is only partly shown in Fig. 5.

according to the constructions illustrat- .ed tlie s'\vab may be readily applied to and removed from advantage ef'this provision in maintaining the swab clean andhsanitary, for, re

the frame An important moved from the frame may be easily handerubbed or put through .a washing ma chine and wrinsger. Substitution of a new swabis also rendered easy, and thusa considerable saving may be effected during the margi nal portions otjthe frame la'ndisubstantially' surrounding the frame, means for holding the swab in readlly releasable relatron to the irame at spaced apart portions of the swab and frame" respectively, the frame "having" oppositely-disposed recesses in a ,marginal portion thereoi intermediate said holding means, and unitary means at said recesses for holding j the swab readily releasably and for drawing portions of it into the space of said recesses respectively to ex e rt a binding action of theswab upon the frame for holding the swab tightly thereon.

2. In a mop or duster ofthe character described, the combination of an elongated tramehaving apair otoppositely disposed recesses in the sides thereof substantially midwayof the ends of the frame, the trame having means at each end for holding a swab thereto so as to lie along marginal portions of the frame-and extend across said recesses,

and clamping, means onthe frame at sad reicesses for drawing portions of the swab toward each other. and into'the space or" the recesses respectively todraw the swab taut uponthe frame.

3. In a mop or duster of the character described, the. combination of an elongated frame of sheet metal having marginal flange at each side thereof and having a pair ofoppositely disposed recesses in the sides substantially midway of the ends ot the il'rame,'the frame having a projection at each end adapted to engage a swab readily releasably, a swab in endless ring form held by said projections and extending along said flanges and across said recesses, and a bolt extending transverse of the frame at .saidrecesses andpassing through the swab for drawing portions of the swab toward .each other to d aw the swab taut upon said Jenn shoves.
